The "adapter" would be a complete PC.

USB is a master/slave protocol (more commonly known a server/client protocol).  
USB devices (i.e. clients) can only talk to a PC running a fairly complex stack 
of device-specific software.   Until a computer master has initialized a USB 
client device and has assigned it an identity, USB devices are completely 
helpless.

There is no practical way to mate USB devices to other USB devices (or to 
non-PC devices such as Kenwood radios, OpenTrackers, TinyTracks, etc) without a 
computer master as middleman.
